Richard Trevithick
Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day.

John Linnell (painter)
John Linnell (16 June 179220 January 1882) was an English engraver, and portrait and landscape painter. He was a naturalist and a rival to the artist John Constable. He had a taste for Northern European art of the Renaissance, particularly Albrecht Dürer. He also associated with the amateur artist Edward Thomas Daniell, and with William Blake, to whom he introduced the painter and writer Samuel Palmer and others of the Ancients. Life and work John Linnell was born in Bloomsbury, London on 16 June 1792, where his father was a carver and gilder. He was in contact with artists from an early age, and by the age of ten was drawing and selling portraits in chalk and pencil. His first art teacher was the American-born artist Benjamin West, and he spent a year in the house of the painter John Varley, where William Hunt and William Mulready were also pupils, and made the acquaintance of Shelley, Godwin and others. In 1805 he was admitted to study at the Royal Academy, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Francis Trevithick
Francis Trevithick (1812–1877), from Camborne, Cornwall, was one of the first locomotive engineers of the London and North Western Railway (LNWR). Life Born in 1812 as the son of Richard Trevithick, he began the study of civil engineering around 1832, and by 1840 was employed by the Grand Junction Railway (GJR). After leaving the LNWR he returned to Cornwall and became factor of the Trehidy estates, of which his grandfather had been mineral agent in the 18th century. He wrote a biography of his father and, in 1872, had it published. He died at Penzance on 27 October 1877 and was buried there. His son, Arthur Reginald Trevithick (1858-1939), worked for many years on the LNWR, including several years as assistant locomotive works manager at Crewe.

Hayle
Hayle (, "estuary") is a port town and civil parishes in England, civil parish in west Cornwall, England, United Kingdom. It is situated at the mouth of the Hayle River (which discharges into St Ives Bay) and is approximately northeast of Penzance. Hayle parish was created in 1888 from part of the now defunct Phillack parish, with which it was later combined in 1935, and incorporated part of St Erth in 1937. The modern parish shares boundaries with St Ives, Cornwall, St Ives to the west, St Erth to the south, Gwinear-Gwithian, Gwinear and Gwithian in the east, and is bounded to the north by the Celtic Sea. History Early history Although there is a long history of settlement in the Hayle Estuary area dating from the Bronze Age, the modern town of Hayle was built predominantly during the 18th century Industrial Revolution. Evidence of Iron Age settlement exists at the fort on the hill above Carnsew Pool where the Plantation now stands. It is thought that Hayle was an impor ...

Consultant
A consultant (from "to deliberate") is a professional (also known as ''expert'', ''specialist'', see variations of meaning below) who provides advice or services in an area of specialization (generally to medium or large-size corporations). Consulting services generally fall under the domain of professional services, as contingent work. The Harvard Business School defines a consultant as someone who advises on "how to modify, proceed in, or streamline a given process within a specialized field". Subject-matter expert vs. consultant According to ''Institute of Management Consultants USA'', "The value of a consultant s compared to a subject-matter expert (SME)is to be able to correctly diagnose and effectively transform an often ill-defined problem and apply information, resources and processes to create a workable and usable solution. Some experts are good consultants and vice versa, some are neither, few are both." Another differentiation would be that a consultant sells adv ...

William Murdoch
William Murdoch (sometimes spelled Murdock) (21 August 1754 – 15 November 1839) was a Scottish chemist, inventor, and mechanical engineer. Murdoch was employed by the firm of Boulton & Watt and worked for them in Cornwall, as a steam engine erector for ten years, spending most of the rest of his life in Birmingham, England. Murdoch was the inventor of the oscillating cylinder steam engine, and gas lighting is attributed to him in the early 1790s, as well as the term "gasometer". However the Dutch-Belgian Academic Jean-Pierre Minckelers had already published on coal gasification and gas lighting in 1784, and had used gas to light his auditorium at the Old University of Leuven, University of Leuven from 1785. Archibald Cochrane, 9th Earl of Dundonald, had also used gas for lighting his family estate from 1789 onwards. Murdoch also made innovations to the steam engine, including the sun and planet gear and D slide valve. He invented the steam gun and the pneumatic tube messag ...

Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Arithmetic
Arithmetic is an elementary branch of mathematics that deals with numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms. Arithmetic systems can be distinguished based on the type of numbers they operate on. Integer arithmetic is about calculations with positive and negative integers. Rational number arithmetic involves operations on fractions of integers. Real number arithmetic is about calculations with real numbers, which include both rational and irrational numbers. Another distinction is based on the numeral system employed to perform calculations. Decimal arithmetic is the most common. It uses the basic numerals from 0 to 9 and their combinations to express numbers. Binary arithmetic, by contrast, is used by most computers and represents numbers as combinations of the basic numerals 0 and 1. Computer arithmetic deals with the specificities of the ...

Village School
One-room schoolhouses, or One-room schools, have been commonplace throughout rural portions of various countries, including Prussia, Norway, Sweden, the United States, Canada, Australia, New Zealand, the United Kingdom, Ireland, Portugal, and Spain. In most rural and small town schools, all of the students meet in a single room. There, a single teacher teaches academic basics to several grade levels of elementary-age children. Recent years have seen a revival of the format. One-room schoolhouses can also be found in developing nations and rural or remote areas undergoing colonization. In the United States, the concept of a "little red schoolhouse" is a stirring one, and historic one-room schoolhouses have widely been preserved and are celebrated as symbols of frontier values and of local and national development. When necessary, the schools were enlarged or replaced with two-room schools. More than 200 are listed on the U.S. National Register of Historic Places. In Norway, by ...

Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The Geology, geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock (geology), rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral or may be an aggregate (geology), aggregate of two or more different types of minerals, spaci ...
